FIELD

Embodiments described herein relate generally to a television apparatusand electronic apparatus comprising a light emitting diode.

BACKGROUND

In an electronic apparatus such as a television, an operation part suchas a button is often illuminated by a light such as a light emittingdiode (LED). Such a light is provided in correspondence with, forexample, a transparent button, and is configured to illuminate theentire button or part of the button. Recently, multiple types of LEDs,which emit light of different colors, have been on the market.

An LED (light) is also often used to display the state of an electronicapparatus. For example, a first light is on while the power is on, asecond light is on while a hard disk is being accessed, a third light ison while wireless communication is being performed, and a fourth lightis on while, for example, an optical disk drive is being driven. In thisway, it is convenient for users to display states of an electronicapparatus using a light or the like. On the other hand, provision of toomany lights is contrary to a demand for reduction in size of anelectronic apparatus and for space saving within a case, and it isdifficult to achieve the balance between the convenience and the demand.

Referring to FIGS. 1-8, a first embodiment of an electronic apparatuswill be described below. As shown in FIG. 1, a television apparatus 11,which is an example of the electronic apparatus of the presentembodiment, is a slim display apparatus having a rectangular appearance.The television apparatus 11 comprises a housing 12 and a leg part 13supporting the housing 12. As shown in FIG. 2, the housing 12 isprovided with a pair of opening portions 14. The television apparatus 11comprises a pair of lenses 15 fitted in the opening portions 14,respectively.

As shown in FIGS. 1 and 2, the television apparatus 11 comprises in thehousing 12: a tuner substrate; a system substrate 21 which collectivelycontrols parts of the television apparatus 11; a printed wiring board 22electrically connected to the system substrate 21 via, for example, aflexible cable; and a flat-shaped display 23. The display 23 is formedof, for example, a liquid crystal display panel, but may be formed ofanother type of display panel, such as a plasma display panel.

As shown in FIGS. 2 and 3, the television apparatus 11 comprises: aplate-like transparent cover 24 covering the surface of the display 23;a plurality of first light emitting diodes 25 provided on the printedwiring board 22; a shade 26 surrounding the first light emitting diodes25; and a plurality of second light emitting diodes 27 provided on theprinted wiring board 22 at positions separated from the first lightemitting diodes 25.

In addition to the first light emitting diodes 25 and second lightemitting diodes 27, a plurality of circuit components 28 are mounted onthe printed wiring board 22 at high density. The printed wiring board 22is provided with an approximately triangular cutout portion 31 formedalong the outer shape of light receiving parts 15B of each of the lenses15, and an edge portion 32 defining the periphery of the cutout portion31.

The first light emitting diodes 25 are aligned on the edge portion 32 ofthe printed wiring board 22. In the present embodiment, three firstlight emitting diodes 25 are provided on the printed wiring board 22,but the number is not limited to three. First light emitting diode 25Aof the first light emitting diodes 25, which is the upper one in FIG. 2,emits, for example, orange light while, for example, a wireless LAN isoperating, thereby notifying a user of the operation. First lightemitting diode 25B of the first light emitting diodes 25, which is themiddle one in FIG. 2, emits, for example, green light while, forexample, a contained optical disk drive is operating, thereby notifyingthe user of the operation. First light emitting diode 25C of the firstlight emitting diodes 25, which is the lower one in FIG. 2, emits, forexample, red light while, for example, a contained hard disk drive isbeing driven, thereby notifying the user of the operation.

As shown in FIG. 2, each of the first light emitting diodes 25 isprovided on an imaginary straight line connecting a display part 15C anda light receiving part 15B of the lens 15, which will be describedlater. Each of the first light emitting diodes 25 is oriented andopposed to the display part 15C of the lens 15. In other words, each ofthe first light emitting diodes 25 is provided to emit light to thedisplay part 15C. The first light emitting diode 25 is aside-lighting-type light emitting diode, which is configured to emitlight parallel to the printed wiring board 22.

As shown in FIGS. 2 and 3, the shade 26 is provided on the printedwiring board 22, and covers the side and top surfaces of the first lightemitting diodes 25 at positions other than the pair of lenses 15. Theshade 26 is provided with a first containing portion 26A which is aconcave formed for containing therein two of the first light emittingdiodes 25, and a second containing portion 26B which is a concave formedfor containing therein one of the first light emitting diodes 25. Theshade 26 separates the first light emitting diodes 25 from the secondlight emitting diodes 27, and prevents, for example, light emitted fromthe second light emitting diodes 27 from being applied to the lenses 15opposed to the first light emitting diodes 25.

The second light emitting diodes 27 are located on the printed wiringboard 22 away from the edge portion 32, i.e., on an approximately centerportion of the printed wiring board 22. In the present embodiment, twosecond light emitting diodes 27 are provided on the printed wiring board22, but the number is not limited to two. Each of the second lightemitting diodes 27 is an upward-lighting-type diode, and is configuredto emit light in a direction crossing (orthogonal to) a direction inwhich the printed wiring board 22 extends. Second light emitting diode27A of the second light emitting diodes 27 emits light, for example,through the cover 24, and notifies the user of the power-on state.Second light emitting diode 27B of the second light emitting diodes 27emits light, for example, through the cover 24, and notifies the userthat the television apparatus 11 is in a power-saving mode, for example.

As shown in FIGS. 2 and 4, each of the lenses 15 comprises: a main part15A shaped like a truncated cone; a plurality of light receiving parts15B protruding from the lower base portion of the main part 15A to thefirst light emitting diodes 25; a display part 15C provided on the upperbase portion of the main part 15A; and a wedge-shaped recess 15Dprovided between the light receiving parts 15B. Further, the main part15A and display part 15C form a light guide part 155 for guiding lightwhich has entered through the light receiving parts 15B to the surfaceof the display part 15C. The main part 15A, light receiving parts 15Band display part 15C are integrally formed of a transparent material,such as an acrylic resin. The main part 15A is fitted in the openingportion 14 of the housing 12.

As shown in FIG. 4, the lens 15 is symmetrical (right-left symmetrical)with respect to a central axis 33 of the main part 15A. In the presentembodiment, the lens 15 is provided with two light receiving parts 15B.As shown in FIG. 2, the light receiving parts 15B are fitted in thecutout portion 31 of the printed wiring board 22 in such a manner as tocorrespond to the first light emitting diodes 25, respectively. Thedisplay part 15C displays light from the first light emitting diode 25,which has entered through the light receiving parts 15B. Asschematically shown in FIG. 5, the display part 15C has a surfaceprocessed (subjected to texturing) to increase surface roughness, andcan diffuse light at the surface.

Light from first light emitting diode 25A is displayed by the displaypart 15C of the upper lens 15 in FIG. 2, and light from first lightemitting diodes 25B, 25C is displayed by the display part 15C of thelower lens 15 in FIG. 2. Since first light emitting diode 25A isprovided at the same angle relative to the lens 15 as first lightemitting diodes 25B, 25C, the amount of light of first light emittingdiode 25A is adjusted to fall within an appropriate range. With thisconfiguration, first light emitting diode 25A is adjusted to look thesame as first light emitting diodes 25B, 25C, thereby preventing theuser from feeling a sense of strangeness.

In the first embodiment, the television apparatus 11 comprises: aprinted wiring board 22 provided with a cutout portion 31; a pluralityof first Light emitting diodes 25 provided on the printed wiring board22 and configured to emit light parallel to the printed wiring board 22;and a lens 15 comprising a plurality of light receiving parts 15B fittedin the cutout portion 31 in such a manner as to correspond to the firstlight emitting diodes 25, respectively, and a display part 15Cdisplaying light which has entered through the light receiving parts15B.

With this configuration, light of the plurality of first light emittingdiodes 25 can be displayed by one lens 15, and the number of lenses 15can be reduced. Consequently, the space occupied by the lens 15 in thetelevision apparatus 11 can be reduced, and the size of the televisionapparatus 11 can be reduced. In addition, since the light receivingportions 15B are fitted in the cutout portion 31, the distance betweenthe first light emitting diodes 25 and the lens 15 can be reduced to theutmost, and light from the first light emitting diodes 25 can beprevented from leaking outside. Further, since the cutout portion 31 isprovided, the lens 15 is prevented from coming into contact with theprinted wiring board 22, and a situation in which the televisionapparatus 11 cannot be properly assembled is prevented.

The printed wiring board 22 comprises an edge portion 32 defining theperiphery of the cutout portion 31, and each of the first light emittingdiodes 25 is provided on the edge portion 32. With this configuration,the first light emitting diode 25 can be located in the vicinity of thelens 15. Therefore, illumination efficiency can be improved, and leakageof light to the surroundings can be suppressed. Moreover, by providingthe first light emitting diode 25 on the edge portion 32, a wide mountarea can be secured on the printed wiring board 22.

The television apparatus 11 is provided with an opening portion 14, andcomprises a housing 12 in which the printed wiring board 22 and thefirst light emitting diodes 25 are contained; the lens 15 comprises amain part 15A shaped like a truncated cone such that a lower baseportion is continuous with the light receiving parts 15B, and an upperbase portion is provided with the display part 15C, the main part 15Abeing fitted in the opening portion 14; and each of the first lightemitting diodes 25 is provided on an imaginary straight line connectingthe display part 15C and a corresponding one of the light receivingparts 15B, and is located to emit light to the display part 15C.

For example, as schematically shown in FIG. 6, when the first lightemitting diodes 25 are located far from the housing 12, the a sufficientdistance between the housing 12 and the first light emitting diodes 25is secured, and light from two first light emitting diodes 25 areemitted to the outside of the housing 12 through the opening portion 14as indicated by chain double-dashed lines. However, as shown in FIG. 7,as a result of promotion of size reduction of the housing 12, when asufficient distance between the housing 12 and the first light emittingdiodes 25 cannot be secured, light from the first light emitting diodes25 does not pass through the opening portion 14 and is blocked by thehousing 12 as indicated by chain double-dashed lines. With theabove-described configuration, for example, the situation shown in FIG.8 is made, and even when a sufficient distance between the housing 12and the first light emitting diodes 25 cannot be secured, sufficientlight can be emitted to the display part 15C. Consequently, betterviewability of light on the display part 15C and reduction in size ofthe housing 12 of the television apparatus 11 can be realized.

The lens 15 is almost symmetrical with respect to the central axis 33 ofthe main part 15A. With this configuration, the light receiving parts15B are located at the same distance from the display part 15C, and atthe same angle with respect to the display part 15C. Therefore, lightfrom all the first light emitting diodes 25 looks the same on thedisplay part 15C.

The television apparatus 11 is provided with a shade 26 provided on theprinted wiring board 22 and surrounding the first light emitting diodes25 at positions other than the lens 15. With this configuration, lightfrom the first light emitting diodes 25 is not diffused to thesurroundings, and illumination efficiency can be improved.

The television apparatus 11 is provided on the printed wiring board 22away from the edge portion 32, and comprises a second light emittingdiode 27 configured to emit light in a direction crossing the printedwiring board 22. With this configuration, high-density mounting can berealized on the printed wiring board 22 by providing the first lightemitting diodes 25 and the second light emitting diode 27 in differentplaces, e.g., providing the first light emitting diodes 25 on the edgeportion 32 and providing the second light emitting diode 27 at aposition away from the edge portion 32 on the printed wiring board 22.
